Question

我正在尝试创建一个使用PHP浏览资产文件夹并作为一种相册系统的图库。下面的代码将文件检索为相册：

<?php
include_once("../PhpScript/RetAlbInfo.php"); 
$files = array_slice(scandir('../Assets/Gallery/'), 2);
for($albflcnt = 0;$albflcnt<count($files);$albflcnt++){
    echo "<div style='...'><div class='albm' style='...' onmousedown='gotoalbum();albnm();'></div><p style='...'>".$files[$albflcnt]."</p></div>";
}
?>

问题是我无法找到从每个<p>标记中获取文件夹名称的方法，并将其附加到网址，以便显示它的子文件夹。

Answer 1

您可以将glob()与GLOB_ONLYDIR选项

一起使用

<?php
foreach (glob("*.txt") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
?>

或

<?php 
    $dirs = array_filter(glob('*'), 'is_dir');
    print_r( $dirs);

 ?>

您可能想要RecursiveDirectoryIterator？不是100％肯定。这是一个基本的例子。有些部分可能相关，也可能不相关。这基本上建立了各种各样的面包屑系统，但可能有你正在寻找的部分：

<?php
# Create some defines in the root of the website if not already done
# This is your url
define('SITE_URL','http://www.example.com');
# This is the root path
define('BASE_DIR',__DIR__);
# This is where everyour files are stored
define('MEDIA_DIR',__DIR__.'/media/');

/*
**  @description    This is just a link builder, there may be some functionality you could use here
**  @param  $path   [string] Relative path
**  @param  $pathStr    [string] Absolute path
**  @param  $append [string | empty]    This is just append to whatever page processes this script
*/
function createLinks($path,$pathStr,$append = '/index.php')
    {
        # Used for the link
        $url    =   SITE_URL.$append;
        # Explodes relative path
        $arr    =   array_filter(explode('/',$path));
        # Loop through to create break crumb
        foreach($arr as $dir) {
            $pathStr    .=  '/'.$dir;
            $new[]      =   '<a href="'.$url.'?goto='.urlencode(base64_encode($pathStr)).'">/'.$dir.'</a>';
        }
        # Return final bread crumb
        return implode('',$new);
    }

# Decodes the path name, you should probably do a more secure encryption / decription method
function getPathFromRequest($path)
    {
        return base64_decode(urldecode($path));
    }
# Set base absolute path
$core   =   MEDIA_DIR;
# Process the absolute path
if(!empty($_GET['goto'])) {
    $base   =   str_replace('//','/',getPathFromRequest($_GET['goto']));
    if(is_dir($base))
        $base   =   $base.'/';
}
else
    $base   =   $core;

# If is a directory, recurse and show the bread crumbs
if(is_dir($base)){
    $skip   =   RecursiveDirectoryIterator::SKIP_DOTS;
    $sFirst =   RecursiveIteratorIterator::SELF_FIRST;
    $dir    =   new RecursiveIteratorIterator(new RecursiveDirectoryIterator($base,$skip),$sFirst);
    # Loop through the file paths
    foreach($dir as $file) {
        $fname  =   $file->__toString();
        if(is_file($fname)) {
            $abs        =   str_replace($base,'',$fname);
            $useType    =   (!empty($_GET['goto']))? $base : $core;
            echo createLinks($abs,$useType).'<br />';
        }
    }
}
else {
    # Redirect to file if is a file
    if(is_file($base)) {
        header('Location: '.SITE_URL.'/'.str_replace(BASE_DIR,'',$base));
        exit;
    }
}

浏览器中的基本视图为您提供了类似的东西（这只是来自我的目录）：

然后html源代码如下：

如果您点击第3或第4个链接中的bkg，则会显示：

单击其中一个将在浏览器中打开该文件。无论如何，你可能对其中的一些，所有这些，或者都没有兴趣！很难猜到你现在拥有的东西和你想要达到的目标。
